In embodiments, such as generally illustrated in FIGS. 1-8, a fluid conduit 20 may include a body 22, a first conduit portion 24 that may be connected to the body 22, a second conduit portion 26 that may be connected to the body 22, and/or a base 30 that may be connected to the second conduit portion 26. A fluid conduit 20 may, for example and without limitation, be configured as, for use with, and/or as a portion of a scavenge pump, an ejector pump, and/or a jet pump that may be used in connection with aircraft.

With embodiments, such as generally illustrated in FIG. 9, a body 22 of a fluid conduit 20 may include a first fluid port 40, a second fluid port 42, and/or a third fluid port 44. The first conduit portion 24 may be connected to and/or extend from the first fluid port 40. The second conduit portion 26 may be connected to and/or extend from the second fluid port 42. The third fluid port 44 may be configured for connection with an external component 46, such as, for example and without limitation, a valve and/or a fluid source (e.g., a fluid pump).

In embodiments, such as generally illustrated in FIG. 9, a body 22 may include a nozzle 48. The nozzle 48 may be connected to and/or extend from the third fluid port 44. The nozzle 48 may extend toward the first fluid port 40. The nozzle 48 may include a cavity 50 and/or a tapered portion 52. The tapered portion 52 may taper radially inward and toward the first fluid port 40 and/or may taper to an aperture 54 of the nozzle 48 that may include a diameter smaller than a diameter of the third fluid port 44. The nozzle 48 may be disposed such that a longitudinal axis 26L of the second conduit portion 26 may extend through the tapered portion 52 of the nozzle 48. The first conduit portion 24, the first fluid port 40, the third fluid port 44, and/or the nozzle 48 may be aligned (e.g., centered) with a longitudinal axis 22L of the body 22, which may be perpendicular or substantially perpendicular to the longitudinal axis 26L of the second conduit portion 26. The body 22 and/or the nozzle 48 may be configured for and/or to cause fluid flow via the Venturi effect.

With embodiments, a body 22 may include one or more flanges, such as a first flange 60 and/or a second flange 62. The first flange 60 may be disposed at or about a first (e.g., front) end 64 of the body 22 and the first conduit portion 24 may extend from the first flange 60. The first flange 60 may be configured for connection with an external component 66, such as a bracket (see, e.g., FIG. 9). The second flange 62 may be disposed at or about a second (e.g., rear) end 68 of the body 22 and the third fluid port 44 may be disposed in or about the second flange 62. The second flange 62 may be configured for connection with a valve 46. For example and without limitation, the second flange 62 may include one or more apertures 70 that may be configured to at least partially receive and/or engage respective fasteners 72 for connecting a valve 46 with the fluid conduit 20. A sealing member 74 may be disposed at least partially between second flange 62 and valve 46.

With embodiments, the first conduit portion 24 may extend from the first fluid port 40 of the body 22. The fluid conduit portion 24 may include one or more of a variety of shapes, sizes, configurations, and/or materials. For example and without limitation, the first conduit portion 24 may be generally cylindrical and may include a first portion 80 and a second portion 82. The first portion 80 may be connected to or extend from the first fluid port 40. The second portion 82 may extend from the first portion 80 and/or may include a larger diameter than the first portion 80.

In embodiments, a second conduit portion 26 may be connected to the body 22 and/or the base 30. The second conduit portion 26 may provide fluid communication between the body 22 and the base 30. The second conduit portion 26 may include one or more shapes, sizes, configurations, and/or materials. For example and without limitation, and as generally illustrated in FIG. 11, the second conduit portion 26 may include a tear drop-shaped configuration (e.g., include a cross-sectional shape) that may include a rounded portion 90 and an angled or pointed portion 92. The rounded portion 90 may be disposed at or about a rear of the second conduit portion 26 and/or the angled or pointed portion 92 may be disposed at or about a front of the second conduit portion 26. A tear drop-shaped configuration may facilitate forming of the second conduit portion 26 via additive manufacturing. The second conduit portion 26 may extend from the body 22 at an angle relative to the first conduit portion 24. For example and without limitation, the second conduit portion 26 may extend substantially perpendicular relative to the first conduit portion 24. The second conduit portion 26 may include a tapered portion 94 that may taper radially outward and toward the base 30. The tapered portion 94 may be disposed toward a rear of the second conduit portion 26 and/or may not be visible from the front. A first conduit portion and/or a second conduit portion may, for example and without limitation, include an outer dimension (e.g., a diameter or width) or about 0.5 inches.

With embodiments, a base 30 may be connected to the second conduit portion 26. A base 30 may include one or more of a variety of shapes, sizes, and/or configurations. For example and without limitation, the base 30 may include a base flange 100 and/or a mesh or cage 102. The base flange 100 may include a circular configuration, but the base flange 100 is not limited to a circular configuration and may include other configurations, such as, for example and without limitation, an oval, a square, a rectangle, and/or triangle configuration. The base flange 100 may be connected to or extend from the second conduit portion 26 and/or the tapered portion 94 of the second conduit portion 26. The base flange 100 may be disposed substantially perpendicular to a longitudinal axis 26L of the second conduit portion 26. In embodiments, such as generally illustrated in FIG. 11, the base flange 100 may include an aperture 104 that may provide fluid communication between the mesh 102 and the second conduit portion 26. The aperture 104 may include one or more of a variety of shapes. For example and without limitation, the aperture 104 may include a generally triangular portion 106 and a generally circular portion 108. The generally circular portion 108 may be at least partially aligned with the second conduit portion (e.g., centered at or around axis 26L) and/or may be disposed toward the front of the fluid conduit 20. Additionally or alternatively, the generally triangular portion 106 may be at least partially aligned with the tapered portion 94 and/or may be disposed rearward of the generally circular portion 108. The generally circular portion 108 may include one or more angled portions 110 that may provide the generally circular portion 108 with a tear drop-shaped configuration. The angled portions 110 may be disposed opposite the generally triangular portion 106.

In embodiments, a base 30 may include a mesh 102 that may extend from the base flange 100. The mesh 102 may include one or more of a variety of shapes, sizes, and/or configurations. For example and without limitation, a mesh 102 may include a plurality of walls that may be disposed in a generally rectangular configuration (e.g., a hollow rectangular prism). The plurality of walls may, for example, include a first wall 120, a second wall 122, a third wall 124, a fourth wall 126, and/or a fifth wall 128. The first wall 120, the second wall 122, the third wall 124, and/or the fourth wall 126 may extend substantially perpendicularly from the base flange 100. The fifth wall 128 may be connected to and/or extend from the first wall 120, the second wall 122, the third wall 124, and/or the fourth wall 126. For example and without limitation, the fifth wall 128 may be configured as a bottom wall. A mesh 102 may include an internal chamber 130 that may be defined by the first wall 120, the second wall 122, the third wall 124, the fourth wall 126, and/or the fifth wall 128 (e.g., the mesh 102 may be hollow). One or more of the plurality of walls may include a plurality of apertures 132 that may be configured to allow fluid to flow into the base 30. The apertures 132 may include one or more of a variety of shapes, sizes, and/or configurations. For example and without limitation, the apertures 132 may be rectangular and/or square and may be disposed to provide a lattice configuration. With embodiments, the base flange 100 may extend (e.g., radially) beyond the mesh 102 in one or more directions. For example and without limitation, the base flange 100 may extend radially beyond the first wall 120, the second wall 122, the third wall 124, and/or the fourth wall 126. The second fluid conduit 26 may or may not be centered on the base flange 100. With embodiments, the second fluid conduit may be off-center relative to the center of the base flange 100 and/or may be disposed toward, at, or about a front of the base flange 100.

In embodiments, a fluid conduit 20 may include a fluid passage 136 (e.g., an internal fluid passage). The fluid passage 136 may extend from the base 30 (e.g., from the mesh 102), through the second conduit portion 26, into the body 22 (e.g., via the second fluid port 42), through the body 22, into the first conduit portion 24 (e.g., via the first fluid port 40), and/or through the first conduit portion 24 to an outlet port 138 of the first conduit portion 24. The third fluid port 44 and/or the nozzle 48 may be in fluid communication with the fluid passage 136. In embodiments, the fluid conduit 20 may be configured to cause, facilitate, and/or allow fluid at or near the mesh 102 to flow through the fluid passage 136 to the outlet port 138.

With embodiments, some or all of a fluid conduit 20 may be formed as a monolithic component (e.g., a single, unitary, integrated piece), such as via additive manufacturing, which may include and/or be referred to as three-dimensional (3D) printing. For example and without limitation, the body 22, the first conduit portion 24, the second fluid conduit 26, and the base 30, and all portions of each (e.g., the nozzle 48, the base flange 100, the mesh 102, etc.), may be formed as a monolithic component. Forming a fluid conduit 20 as a monolithic component may allow the fluid conduit 20 to be void of any joints and/or internal fluid seals, such as to seal joints between components. For example and without limitation, a fluid conduit 20 may not include fluid sealing members between any of the body 22, the nozzle 48, the first conduit portion 24, the second conduit portion 26, the base 30, the base flange 100, or the mesh 102). Additionally or alternatively, forming a fluid conduit 20 as a monolithic component may allow the fluid conduit 20 to be connected together (e.g., originally formed) without fasteners, welding, joining, or other connection components or methods.

In embodiments, such as generally illustrated in FIGS. 12, 13A, and 13B, a fluid conduit 20 may be made or formed via additive manufacturing, which may include forming a fluid conduit 20 via sets of layers. The body 22, the first conduit portion 24, the second conduit portion 26, and/or the base 30 may be formed via sets of layers. For example and without limitation, a fluid conduit 20 may be formed via a first set of layers 140, a second set of layers 142, a third set of layers 144, a fourth set of layers 146, and/or a fifth set of layers 148. A fluid conduit 20 may be formed starting with a rear of the fluid conduit 20 and formed progressively toward the front of the fluid conduit 20 (e.g., may not be formed from bottom up or from top down). A set of layers may include one or more layers (e.g., 1 layer, 10 layers, 37 layers, 1,000 layers, etc.).

With embodiments, such as generally illustrated in FIGS. 13A-17, making or forming a fluid conduit 20 may include forming one or more supports that may be used for at least temporarily supporting one or more portions of a fluid conduit 20 during manufacture or formation. For example and without limitation, forming a fluid conduit 20 may include forming a first support 150, a second support 152, a third support 154, and/or a fourth support 156.

With embodiments, such as generally illustrated in FIGS. 12, 13A, and 13B, a method 160 of forming a fluid conduit 20 may include forming a first set of layers 140 (step 162), such as one a surface (e.g., a planar surface of a powder bath). A first set of layers 140 may include portions or parts of the first support 150, the second support 152, the third support 154, and/or the fourth support 156, and may or may not include any other portions (e.g., a first set of layers 140 may include only supports that may be later removed and may not include any portion of a final fluid conduit). A second set of layers 142 may be formed, such as on top of the first set of layers 140 (step 164). A second set of layers 142 may include portions or parts of the first support 150, the second support 152, the body 22, and/or the base 30, and may or may not include any other portions. The second set of layers 144 may include portions or parts of the second flange 62 of the body 22, the base flange 100, and/or the mesh 102 of the base 30. A third set of layers 144 may be formed, such as on top of the second set of layers 142 (step 166). The third set of layers 144 may include portions or parts of the first support 150, the second conduit portion 26, and/or the base 30, and may or may not include any other portions. The third set of layers 144 may include portions or parts of the nozzle 48 of the body 22, the base flange 100, and/or the mesh 102 of the base 30. A fourth set of layers 146 may be formed, such as on top of the third set of layers 144 (step 168). The fourth set of layers 146 may include portions or parts of the first support 150 and/or the body 22, and may or may not include any other portions. The fourth set of layers 146 may include portions or parts of the first flange 60 of the body 22. A fifth set of layers 148 may be formed, such as on top of the fourth set of layers 146 (step 170). The fifth set of layers 148 may include portions or parts of the first conduit portion 24, and may or may not include any other portions.

In embodiments, such as generally illustrated in FIGS. 14-16, a first support 150 may be formed to support a first flange 60 of the body 22. The first support 150 may include one or more columns 180 (e.g., four columns 180 A, 180B, 180C, 180D) that may include one or more column sections 182. For example and without limitation, a column may include seven column sections (e.g., column 180A may include column sections 182Ai, 182A2, 182A3, 182A4, 182A5, 182A6, 182A7). The column sections 182 may be generally planar, may be disposed in parallel with each other, and/or may be disposed at a distance from each other such that there may be a gap between one or more column sections 182. One or more column sections 182 may include a tapered portion 184 disposed at or about the first flange 60. The tapered portions 184 may be configured to facilitate removal and/or disconnection of a column 180 from the first flange 60, such as once formation is complete (e.g., during step 174 of method 160).

In embodiments, such as generally illustrated in FIGS. 13A, 13B and 15-17, a second support 152 may be formed to support a second conduit portion 26. A second support 152 may include one or more legs 190 that may be disposed in a first set or rows (e.g., rows 192A, 192B, 192C, 192D) and/or a second set of rows (e.g., rows 194A, 194B, 194C, 194D). The first set of rows may be disposed at a first side of a longitudinal axis 26L of the second conduit portion 26 and/or the second set of rows may be disposed at a second, opposite side of the longitudinal axis 26L of the second conduit portion 26. The first set or rows and/or the second set of rows may include, for example and without limitation, four rows. A row may include one or more legs 190. For example and without limitation, the first set of rows and/or the second set of rows may include outer rows (e.g., rows 192A, 192D, 194 A, 194D) that may include three legs 190 and inner rows (e.g., rows 192B, 192C, 194B, 194C) that may include five legs 190. The legs 190 in rows of a set of rows may or may not be aligned (e.g., in a longitudinal direction of the second conduit portion) with each other. For example and without limitation, legs 190 in outer rows may be at least partially offset from each other, legs 190 in inner rows may be aligned with each other, and/or legs in inner rows may be at least partially offset from legs in outer rows.

With embodiments, such as generally illustrated in FIGS. 13A, 13B, and 15-17, a third support 154 may be formed to support a base 30. The third support 154 may include a first section 200 and/or a second section 202. The first section 200 may be solid, may extend in a longitudinal direction (e.g., parallel with axis 26L), may be connected to the base flange 100, and/or may be connected to the mesh 102. The second section 202 may include a plurality of fins 204 that extend from and/or be connected to the base flange 100. The fins 204 may be generally planar and may be spaced from each other. The fins 204 may have different heights, such as to provide a generally arc-shaped configuration that may correspond to an outer edge of the base flange 100. One or more of the fins 204 may include a tapered portion 206 disposed at or about the base flange 100. The tapered portions 206 may be configured to facilitate removal and/or disconnection of the fins 204 from the base flange 100, such as once formation of the fluid conduit 20 is complete (e.g., in step 174 of method 160).

In embodiments, such as generally illustrated in FIGS. 13A, 13B, 14, 16, and 17, a fourth support 156 may be formed to support the body 22. The fourth support 156 may extend from and/or be connected to the second flange 62 of the body 22. For example and without limitation, the fourth support 156 may effectively be configured as an extension of the second flange 62.

In embodiments, some or all of forming a fluid conduit 20 may be conducted in a powder bed. It may be desirable to remove powder 210 from one or more portions of a fluid conduit 20 (see, e.g., FIG. 13B). Forming a fluid conduit 20 may include removing powder 210 from a fluid conduit 20 (e.g., in step 172 of method 160), such as prior to removal of some or all supports. Gravity may be utilized in some cases to remove powder 210. Additionally or alternatively, fluid (e.g., pressurized air) may be provided to or removed from (e.g., via negative pressure and/or a vacuum) a fluid conduit 20 to remove powder 210. For example and without limitation, and as generally illustrated in FIGS. 16 and 17, the fourth support 156 may include one or more channels 212, 214, and a cavity 216 that may be in fluid communication with the nozzle 48 (e.g., forming fourth support 156 may include forming the one or more channels 212, 214 and/or the cavity 216). The cavity 216 of the fourth support 156 may be partially or completely aligned with the cavity 50 of the nozzle 48. The one or more channels 212, 214 may be connected to a fluid source and may provide fluid to the cavity 216 and into the body 22, and the fluid may flow within the body 22 and/or cavities 50, 216. In some cases, such as with fourth supports 156 having a single channel 212 or 214, the fluid may cause powder 210 in the body 22 to move through the nozzle 48 and out through the first conduit portion 24 (or fluid may be provided to the nozzle 48 and powder 210 may exit via the channel 212 or 214). In other cases, such as with fluid conduits 20 having a fourth support 156 including a first channel 212 (e.g., an inlet channel), a second channel 214 (e.g., an outlet channel), and/or a aperture 54 of a nozzle 48 at least temporarily blocked, fluid may be provided from the fluid source to the inlet channel 212, the fluid may flow through the cavity 216 and into the body 22, and the fluid may cause powder 210 in the body 222 to move through (e.g., down) the cavity 216 and out through the outlet channel 214. It should be understood that references to powder 210 are not necessarily limited to powder and could include other materials or substances, such as dust, debris, or other foreign matter.

In embodiments, forming a fluid conduit 20 may include removing one or more supports (step 174). Removing supports may include removing a first support 140, a second support 142, a third support 144, and/or a fourth support 146.
